ABSTRACT
Objective: To assess the frequency of sarcopenia in type 2 diabetes mellitus [DM] patients using different formulas of bioimpedance analysis [BIA]
Study Design: Cross-sectional study. Place and Duration of Study: Obesity Clinic, Kartal Dr. Lutfi Kirdar Training and Research Hospital, Istanbul, Turkey, between March and June 2015
Methodology: The present study included DM patients at >/= 18 years of age with BMI >/= 30 kg/m[2]. BIA measurements consisted of body weight, height, total muscle mass and sum of the muscle masses of the four limbs [ALM]. Skeletal muscle index, total muscle index, skeletal muscle percentage, total muscle percentage, and ALM/BMI were used for muscle-related analyses. The data were presented as frequency, mean +/- standard deviation, and percentage. Student t-test was used to compare differences between two independent groups
Results: A total of 295 DM patients were enrolled in the study, of whom 176 [59.66%] were females, 119 [40.34%] were males, 47 [15.93%] were over the age of 65 years, and the mean age was 53.39 +/- 10.39 years. Sarcopenia was determined in 40 males [33.61%] by body muscle ratio, in 15 males [12.60%] by ALM/BMI ratio, and in one male participant [0.84%] by skeletal muscle index. Among female participants, while sarcopenia was determined in 61 [34.65%] by body muscle ratio and in 1 [0.56%] by ALM/BMI ratio, no sarcopenia case was detected using skeletal muscle index
Conclusion: The frequency of sarcopenia in obese diabetic patients is found to be lower when skeletal muscle index and ALM/BMI ratio is used, but higher with body muscle ratio
